Self-reported attribution: ask your buyers how they found you
There is a category of attribution data that no tracking pixel, UTM parameter, or multi-touch model can capture: the thing the buyer actually remembers. A founder who has been following your newsletter for two years, saw you speak at a conference, heard you on a podcast, and then searched for you directly six months later will show up in your analytics as direct/none. The real answer — "I have been following Ewoud's newsletter since 2024" — is sitting in your buyer's head, and the only way to get it is to ask.
Self-reported attribution is a single open-text field on your demo request form, trial signup page, or post-purchase survey: "How did you first hear about us?" That is the whole method. The data it surfaces is routinely the most strategically useful attribution signal a B2B founder has, because it captures the dark social channels — podcasts, word-of-mouth, communities, LinkedIn posts — that are invisible to any tracking architecture but often drive a disproportionate share of the best buyers.
The analysis is straightforward: collect the responses, clean the language ("I heard you on the Indie Hackers pod" and "Indie Hackers podcast" are the same channel), and look at which channels are named by the customers with the highest ACV, longest retention, and fastest close. That pattern tells you where to invest attention, not just where to spend budget.
A solo founder running a £200k ARR B2B product used self-reported attribution to discover that 40% of their closed revenue traced back to two podcast appearances and a single viral LinkedIn post — none of which showed up in paid attribution models because they drove direct and branded search, not click-through. The channel investment decision that followed was obvious once the data was visible.
The self-reported attribution playbook covers the question wording, form placement, response cleaning, and how to weight self-reported data alongside your server-side event data to build an attribution picture you can actually act on.
